About the Front Panel Controls

Most of the Duo-i

plus

functions are operated by the three controls

on the front panel.

Power/Volume – Is controlled by the large knob in the center of

the panel.

Mode – Selects the input you want to use or the function you

want to adjust.

Tune – Tunes in a new radio station.

These logical, intuitive controls make it easy to operate the Duo-i

The way you use each contol is the same for each feature. Once

you learn how to control one of the features the rest of them

will be easy. You may not need to refer to this manual once you

understand the way the controls work.

About the Remote Control

Most of the features of the Duo-i

The remote also has a magnetic backing so it can be attached to many metal

surfaces.

Note: When you unpack your remote control there will be a plastic insulation
